A process for conditioning basic oxygen steelmaking process dust and fume containing heavy metals for disposal. A sufficient quantity of solidified basic oxygen steelmaking process slag particles are added to the dust and fume to produce a mixture having an alkalinity substantially greater than that of the dust and fume alone. The dust and slag mixture tests as non-hazardous when tested using the toxicity test procedures for heavy metals promulgated by the United States Environmental Protection Agency (EPA).
